This is an old revision of the document!
In the past, when you added either positioning, training, or office duty (duties with the or the icon) - the number of items in the 'Legs Info' screen was the same as when adding a new flight. In other words, items were those defined in Admin > Operator Settings > Flight Editing section.
From now the number of items for such duties is reduced to minimum by default. Please see examples below.
